Add router modules in Zend

Question

I have this code:

$defaultAdmin = array ('module' => 'admin', 'controller' => 'index', 'action' => 'index' );
$routeAdmin = new Zend_Controller_Router_Route ( 'admin/:controller/:action/*', $defaultAdmin );
$router->addRoute ( 'admin', $routeAdmin );

However, if I get into this url: /admin/ it load the controller on /application/controllers/IndexController.php instead of the one in /application/modules/admin/controllers/IndexController.php

My full bootstrap is this one:

abstract class My_Application_Bootstrap extends Zend_Application_Bootstrap_Bootstrap {
    /**
     * Inicializa las características generales de la aplicación
     *
     * @param $application Zend_Application|Zend_Application_Bootstrap_Bootstrapper         
     * @return void
     */
    public function __construct($application) {
        parent::__construct ( $application );

        $autoloader->registerNamespace ( 'Busca' );
        $this->_initConfig ();

Answer 1

Create a new directory in application folder name 'modules/default' , cut paste your 'application/controllers' inside it . Then make sure your application.ini have

resources.frontController.moduleDirectory = APPLICATION_PATH "/modules"
resources.modules = true;

If you keep 'controllers' directory inside application folder then zf will not use modular structure hence make sure you cut and paste.

Answer 2

once you have your module based structure, be sure to create a bootstrap for your module with your custom routes. for example

class Example_Bootstrap extends Zend_Application_Module_Bootstrap
    {

    public function _initModuleRoutes()
    {
        $this->bootstrap('FrontController');
        $frontController = $this->getResource('FrontController');
        $router = $frontController->getRouter();

        $route = new Zend_Controller_Router_Route(
            'modulename/:action/*',
            array(
                    'module' => 'modulename',
                    'controller' => 'modulecontroller',
                    'action' => 'index'
            )
        );
        $router->addRoute('routename', $route);

        return $router;
    }
